New research has uncovered why different climate models offer varying projections of sea surface temperature (SST) changes in ...

Radioactive spike found in Pacific seabed samples. It could be from space radiation or changes in ocean currents 10 million years ago.

Our own bodies - muscles, bones, and tissue - contain naturally occurring radioactive elements. Man has always been exposed to natural radiation arising from the earth as well as from outside the ...

In their ability to penetrate matter and displace electrons in atoms and molecules, the various forms of this radiation have deep significance for science, technology and the future of man ...

One of the new belts found by CIRBE fit this pattern. However the other belt contained a substantial abundance of high-energy protons, too (protons are found also in the permanent radiation belts).

What is meant by radiation “dose” of X rays? Radiation dose is a measure of how much energy is absorbed when something or someone is exposed to X-rays. This is important because it is this absorption ...
